Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a POS system, and more particularly to a POS system capable of processing information relating to discounts.

[0002]

2. Description of the Related Art As a system for managing sales information, a POS system has recently become widespread in retail stores and the like. In this POS system, a selling price is determined by reading a barcode attached to a product. In recent years, services provided at retail stores and the like have been diversified, and among them, a price reduction service is one of frequently provided services.

There are the following modes for providing a discount service using the POS system. As a first method, a normal price is displayed and a discount seal is attached to a product and a product tag. In this case, the operator who operates the POS device confirms the discount amount by looking at the discount seal, and inputs the discount amount from a keyboard connected to the POS control unit. At this time, the POS control unit searches the barcode data for pre-discount price information of the product, subtracts the input discount amount from the pre-discount price, determines and displays the discount price, and the like.

The second method is disclosed in Japanese Patent Laid-Open No. 8-212.
No. 459 discloses a discount method. In this method, a discount amount is written on a barcode and a discount process is performed. A third method is a discount method disclosed in Japanese Patent Application Laid-Open No. 63-232133. In this method, when a discount occurs, the label is read using a handy-type portable barcode label processing device, the read amount and the amount specified by the discount method are subtracted, and the barcode label is re-read using this data. Issued.

A fourth method is disclosed in Japanese Patent Laid-Open No. 8-772.
There is a discount system disclosed in Japanese Patent Publication No. 56-56. This method uses discount period, discount price, discount rate, etc.
Information on sales conditions that change depending on time, time, and the like is described in a multidimensional barcode, and a discount service or the like is provided by reading the multidimensional barcode.

[0006]

The conventional POS described above
The system had the following problems. According to the first method, the determination of the discount amount or the like at the time of settlement depends on the input of the operator, and it is not possible to avoid mistakes completely, and it is troublesome to perform the input operation sequentially. In the second method, in the case of a barcode input device that moves a product usually used in a supermarket or the like onto a laser irradiation window of a scanner and reads the barcode, a barcode describing discount information may not be read. . As described above, if the bar code cannot be read, the product cannot be discounted and the customer's trust is lost.

Further, according to the third method, data before discount is read by a scanner, a discount calculation is performed, and a bar code label created with new data is attached.
The system does not know the data before the discount. for that reason,
There was a problem that the customer did not know how much the discount had been made. According to the fourth method, various information can be written by using a multidimensional barcode. However, the use of a multidimensional barcode as a POS system is not widely performed, and a unique hardware is required. It must be configured and lacks versatility.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a POS system which is highly reliable for customers without a mistake in discounting with a simple configuration.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a barcode creating apparatus for creating a barcode including discount information on a product, and a barcode creating apparatus for creating a barcode. A POS system including a POS device that reads barcode information and performs a settlement process, wherein the barcode creation device reads barcode reading means for reading a barcode of a product before discounting, and reads the barcode. A bargain amount input unit for inputting a bargain amount for a product, and a barcode including pre-discounting merchandise information and bargain amount information based on the barcode read by the barcode reading unit and the bargain amount input by the bargain amount input unit. And a barcode output means for outputting the created barcode. The POS device includes a POS barcode reading unit that reads a barcode, and a barcode that determines whether the barcode read by the POS barcode reading unit includes the discount amount created by the barcode creation unit. Discriminating means, and a price for calculating a discounted price based on the read barcode information when the barcode read by the barcode discriminating means is determined to include the discount amount information. It is configured to include a calculating unit and a price output unit that outputs the post-discount price calculated by the price calculating unit together with the pre-discount price.

That is, the present invention comprises a barcode creation device for creating a barcode including discount information of a product, and a POS device for reading the barcode information created by the barcode creation device and performing a settlement process. The customer pays for the merchandise purchased by the customer while discounting the merchandise with a POS device. Therefore, the barcode reading means of the barcode creation device reads the barcode of the product before the discount, and the discount amount input means inputs the discount amount for the product from which the barcode has been read.

The bar code reading means reads the bar code of the product before the discount and inputs the discount amount by the discount amount inputting means. Based on the bar code read by the bar code creating means and the inputted discount amount, the bar code before the discount is input. Create a barcode containing product information and discount amount information. When the barcode creation means creates a barcode including the pre-discount product information and the discount amount information, the barcode output means outputs the created barcode. Therefore, it is possible to process the discount information in the POS device by attaching the created barcode label or the like to the product.

The POS bar code reading means of the POS device reads a bar code, and the bar code discriminating means prepares the bar code read by the POS bar code reading means by the bar code preparing means. It is determined whether or not the discount amount is included. When the barcode determining means determines that the read barcode includes the discount amount information, the price calculating means calculates the discounted price based on the read barcode information.

Further, the price output means outputs the post-discount price calculated by the price calculation means together with the pre-discount price. Therefore, it is possible to cope with the discount service at the time of settlement, and it is clearly shown that the discount service is being performed.

Here, the bar code creation means of the bar code creation device only needs to be able to create a bar code including discount amount information, and various configurations are conceivable. As an example of the configuration, in the invention according to claim 2, in the POS system according to claim 1, the barcode creation means of the barcode creation device has a barcode of a standard different from a standard barcode for a commodity. And the POS bar code reading means of the POS device is capable of reading a bar code of a standard different from the standard bar code for a commodity.

That is, the barcode handled when processing in the POS system is standardized, and the barcode creation means of the barcode creation device creates a barcode of a standard different from that of a normal product barcode. . Since the POS bar code reading means of the POS device can read a bar code of a different standard from the normal bar code for merchandise, the bar code of the different standard is read to reduce the price. It is possible to handle information.

Here, there are various modes when a barcode of a standard different from that of a normal product barcode is prepared, and as an example of the configuration, the invention according to claim 3 is as follows.
In the POS system according to claim 1 or 2, the bar code creation means adds a discount amount information to information of a normal bar code for a product, so that the bar code creating unit differs from the bar code of the normal standard. The bar code is created.

That is, the information included in the normal bar code for a product includes the price before the discount of the product, the name of the product, and the like, and this information is also used in the POS system according to the present invention. Therefore, the barcode creating means creates a barcode of a standard different from the normal standard barcode by adding discount amount information to the information of the normal product barcode. As a result, it is possible to perform the discount processing while enabling the processing by the conventional POS system.

Further, as a more specific example of the bar code of the normal product standard and a standard different from that of the normal product, the POS system according to any one of claims 1 to 3 is provided. In the above, the bar code reading means of the bar code creating apparatus reads a JAN standard bar code which is a normal product bar code, and the bar code creating means creates a CODE 128 standard bar code.
The POS barcode reading means of the OS device is CODE12
It is configured to be able to read eight standard bar codes.

That is, since the JAN standard is commonly used as a barcode standard for ordinary products, the barcode reading means of the barcode creation device reads a JAN standard barcode which is a normal barcode for products. It is designed to read. Here, in the JAN standard, data is 1
Since only three digits can be handled, it is preferable to use a barcode standard having more digits than the JAN standard in order to use discount information.

Therefore, the bar code creation means of the bar code creation device creates a CODE 128 standard bar code, and the POS bar code reading means of the POS device uses CO code.
It is possible to read a bar code of the DE128 standard. Therefore, the POS device can handle the discount information in spite of the predetermined standard of CODE128.

As described above, the POS system according to the present invention can handle discount information.
It is desirable to clearly show that customers are offering discount services at the time of settlement. Therefore, as an example of a configuration for clearly indicating that the discount service is being performed, the invention according to claim 5 is a POS system according to any one of claims 1 to 4, wherein the price of the POS device is reduced. The output means is configured to display the pre-discount price and the post-discount price so that the customer can visually recognize the product during payment.

That is, when performing a settlement process in a POS system, the prices of individual commodities are generally made visible to customers. Therefore, in order to clarify that the discount is being performed, the price output means of the POS device displays the pre-discount price and the post-discount price so that the customer can visually recognize the product during payment. As a result, it is possible for the customer to visually recognize whether or not a discount has been made for each product, and it is possible to prevent the store from giving the customer an unnecessary distrust.

Further, as a specific example for more clearly showing the contents of the discount service to the customer, the invention according to claim 6 is the PO according to any one of claims 1 to 5.
In the S system, the price output means of the POS device is configured to output a receipt on which the pre-discount price and the post-discount price are printed after the goods are settled.

That is, in most cases, after the payment processing is performed in the POS system, a receipt is issued to the customer. Therefore, in order to clarify that the discount is being performed, the price output means of the POS device outputs a receipt on which the price before the discount and the price after the discount are printed after the settlement of the commodity. As a result, it is possible for customers to confirm in writing whether or not a discount has been made for each product, and it is possible to easily confirm the service content even after a predetermined time has elapsed since the settlement. Becomes possible.

If it is not determined that the discount format includes the pre-discount price and the discount amount, the barcode data is discarded (step S940).

When it is determined in step S930 that the discount format includes the pre-discount price and the discount amount, a settlement process is performed in consideration of the discount amount (step S950). Here, in step S950, when performing the settlement process, the display unit 150 displays the pre-discount price and the post-discount price, and the printer unit 300 displays the pre-discount price and the post-discount price on the receipt passed to the customer. Is printed.

The operation of the present invention based on the above configuration and flow will be described below. When discounting merchandise at a mass retailer such as a supermarket, there are mainly the following two cases. First, the first discount method is a case where the price of a certain product is reduced by a fixed amount for a fixed period of time, such as when the product is sold. In this case, since the information of the price reduction is known in advance, the price and the period of the discount information are described in the product information data file, so that the discount can be performed for a certain period of time.

As a second discount method, a 100-yen discount sticker or a half-price sticker is attached immediately before closing a store for the purpose of selling out the product as a fresh product or the like. There is a case where the price of the product is discounted by adding a tag. In this discount, the discount period is not fixed, and the discounted product to be discounted, the discount amount, and the like are variously determined by the clerk. The discount targeted by the present invention is suitable for use in the case of the second discount.

As described above, when the salesperson of the perishable goods or the like discounts the price, the operator operates the barcode input unit 600 of the barcode creation device 500 in the present embodiment.
A JAN standard barcode for a normal product attached to the product to be discounted is read. Further, when the operator inputs the discount amount by operating the operation panel unit 540 or the like, the CPU 510 creates a CODE128 standard barcode from the information based on the barcode read by the barcode input unit 600 and the discount amount, At 700, a barcode label is printed. The barcode label printed at this time conforms to the CODE128 standard, and includes discount information.

When the customer purchases the barcode-labeled product and carries the product to the supermarket cash register, the cashier determines whether the discount has been made or not. The settlement process can be performed without any awareness. That is, the cashier reads the barcode attached to the product using the barcode input unit 200 connected to the POS device. At this time, the CPU 110 of the POS device 100 determines in step S910 whether or not the barcode is created by the above-described barcode creation device 500. It can be performed.

When the CPU 110 performs the settlement process, the bar code data unique to the product is used as a key code to search the product information data file held in the external storage unit 400 for product information such as the price and name of the product. . here,
When the product is provided with a barcode including discount information according to the CODE128 standard, the display unit 1
The settlement process is performed while displaying the pre-discount price and the post-discount price by 50. Further, the pre-discount price and the post-discount price are also printed on the receipt to be given to the customer. Therefore, it is possible to clearly show that the customer is discounting.

As described above, according to the present invention, when it is desired to provide a discount service, the barcode creating apparatus creates a barcode label in which discount information is added to information on a pre-discount product. Then, at the time of settlement by the POS device, the created barcode label is read, and the settlement is performed while clearly indicating the price before discount and the price after discount to the customer. Therefore, it is possible to provide a highly reliable POS system for customers without a discount error due to a simple configuration.
